Deep Insanity

Deep Insanity is a Japanese mixed-media project created by Square Enix. It is set in a world where a large part of the population has fallen into comas from a mysterious illness called Randolph Syndrome, which is traced to a place under the South Pole called Asylum, where people go to look for a cure or for treasure. The earliest dated release is the manga Deep Insanity: Nirvana, serialized in Monthly Big Gangan from January 2020 to March 2023 with art by Etorouji Shiono. A mobile and PC action role-playing game, Deep Insanity: Asylum, was released in Japan on October 14, 2021 and ended service on October 31, 2022. An anime television series by Silver Link, Deep Insanity: The Lost Child, aired from October to December 2021 and is set between the manga and game storylines. A Twitter-based interactive game about a reporter trapped in a hospital also ran for three weeks in July 2021.
